Perfect confidence

The emotional impact of the Royal 201 diamond cut is perfect when you are the canvas. The exclusively designed open setting of the Royal 201 C Collection allows even more light to pass through, maximizing the brilliance of the 201 facets to shine on your bare skin. Feel confident by wearing the perfectly cut diamond in a unique designed setting. 

At the heart of the Signature C Collection design is a manifestation of the letter C. Not only a reference to Royal Coster Diamonds - the trusted and renowned diamond house established in 1840 - It is also a reference to quality. The 4 C's, a standard in the diamond industry indicating the quality of diamonds, and the 5th C, which stands for Confidence. The C is incorporated in the design so that the opposite ends act as a base, creating a perfect stage for the center Royal 201 stone to shine.

A wonderful starting point to maximize the effect of our perfectly cut diamonds, always supporting the emotional impact of the Royal 201 itself.

Polishing the Royal 201

The first Royal 201 was cut in 2007. Diamonds for the Royal 201 are hand selected and cut by hand. The master polishers evaluate each stone for imperfections to begin with the most perfect canvas possible. The sharpening of the Royal 201 takes twice as long as a conventional round brilliant cut and is done in three stages. There are no Royal 201 diamonds smaller than 0.2 carats; this to get the right balance between size and impact. Today, a large team of professionals, including 18 sharpeners specially trained to sharpen the Royal 201, are working to create the Royal 201.
